How we handle Computers
- What these guides cover
- Working out whether a fault is software, hardware or heat before changing anything, using tools already built into Windows and macOS.
- Where we stop
- We do not recommend registry cleaners, driver updaters or optimiser utilities, and we do not walk through opening a machine still under warranty.
- Safety line
- Where a symptom can mean a failing drive, we say stop and copy your data off first. Carrying on diagnosing can cost you the data.
- What we check against
- Microsoft and Apple support documentation, and the machine's own logs.
